Aronian Crashes Out In Kazan

There was high drama in Kazan today as the favourite for the event tumbled out, and another was quite possibly saved by a malfunctioning clock.

Aronian started badly against Grischuk, losing the first rapid game with the white pieces but he hit back immediately to level the scores in game two.

After a draw in the third game, Grischuk upset the odds in game four and broke Armenian hearts as the knocked the world's #3 rated player out of the Candidates.

Even greater drama was to come in the other tie-break match, where Kramnik and Radjabov were still inseparable after drawing all four rapid tie-break games. Radjabov finally broke the deadlock to win the first blitz game, meaning that Kramnik had to win the next game or be eliminated. After 60 moves of the second blitz game a draw seemed on the cards, but then something incredible happened - the electronic clock malfunctioned!

After a break of several minutes, during which time the problem was resolved, the players sat down again to resume the game and incredibly Kramnik found a way to win and stay in the match!

After this remarkable stroke of serendipity, Kramnik held his nerve to take the next two blitz games to qualify for the semi-finals.

So we now know that the next challenger for Vishy Anand's world title will either be:

a Brooklynite...

older than Anand...!

a semi-professional poker player

or Kramnik again!

How are your own predictions going so far? Is your favourite still in the contest? Who do you want to win, and will any of them have a chance in a world championship match with Anand?
